Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear (depending on where the issue is) of the vehicle.
Secure with jack stands to ensure safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Keep lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads; if less than 3mm, replace them.
Replacement:
1. Remove the caliper bolts using a socket wrench.
2. Slide the caliper off the rotor and support it (do not let it dangle from the brake line).
3. Remove the old pads from the caliper bracket.
4. Install new brake pads into the caliper bracket, ensuring they are seated correctly.
5. Push the caliper piston back using a brake caliper tool to create space for the new pads.
6. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (usually 20-30 ft-lbs).

5. Inspect and Replace Brake Rotors (if necessary)

Inspection: If rotors are scored or warped, they should be replaced.
Replacement:
1. Remove the retaining screws (if applicable) and slide the rotor off the hub.
2. Clean the hub surface with a wire brush to remove any rust.
3. Install the new rotor and secure it with retaining screws (if applicable).

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).

7. Test the Brake System

Pump the brake pedal a few times to ensure proper brake pressure.
Conduct a low-speed test drive to confirm functionality.
